2021-the present: Indigenous People, Traditional Ecological Knowledge, and Climate Change: The Iconic Underwater Cultural Heritage of Stone Tidal Weirs 
Organization which operates under the United Nation Decade of Ocean Science for Sustainable Development (2021-2030). The lead university is Tokyo University of Marine Science and Technology (project leader), other partner institutions together with Nelson Mandela University are the University of Guam, University of Warsaw, Chikushi Jogakuen University, Mokpo National University, University of the Philippines and Trinity College.   
Aim: The underwater cultural heritage of stone tidal weirs is a type of fish trap operated only by tidal amplitude. Stone tidal weirs are completely submerged during high tide, while they emerge into full view at low tide, allowing people collect fish. This tangible, intangible, or living cultural heritage is the most vulnerable against climate change, in particular, against ocean climate change. Many are ‘now’ disappearing rapidly in front of us before researchers study them or the national and local governments start to protect them properly. The aim of the working group is to document and to study, in coordination with the local communities, those sustainable structures.  
This Project is hosted under the Decade Programme Cultural Heritage Framework
